Heya, I was also raised with "goto = evil" and it took me some decades to overcome this mantra/early brainwash. Hereto, Linus' "while+goto looks more beautiful in assembly" was important for me (https://koblents.com/Ches/Links/Month-Mar-2013/20-Using-Goto-in-Linux-Kernel-Code/).
I did not exactly follow the seeds of this exchange, and likely will not get all the details if I tried, but 10 please allow GOTOs in. 20 goto 10 Cheers, Steffen > Gesendet: Donnerstag, 24.
